The development of an efficient protocol for the reductive functionalization of amides into pyrimidinediones and amino-substituted thioacrylamides is presented. Enamines are generated in a highly chemoselective amide hydrosilylation reaction catalyzed by molybdenum hexacarbonyl in combination with 1,1,3,3-tetramethyldisiloxane. The direct addition of either isocyanate or isothiocyanate generates the
提出了将酰胺还原功能化为嘧啶二酮和氨基取代的硫代丙烯酰胺的有效方案的开发。在六羰基钼与1,1,3,3-四甲基二硅氧烷结合催化的高度化学选择性酰胺氢化硅烷化反应中生成烯胺。异氰酸酯或异硫氰酸酯的直接添加以高收率产生相应的嘧啶二酮和3-氨基硫代丙烯酰胺。
